The pier and foreshore, about 40 kilometres south-east of Melbourne’s CBD, were cordoned off on Saturday while detectives from the homicide squad investigated the crime scene.
Fisherman Francisco Quiroz, who fishes at the pier almost every day, said the Frankston foreshore could be unsafe for visitors at night.
“A lot of drugs, a lot of people drunk and all that … and looking for trouble,” Quiroz told Nine News.
Police believe the man who died and the man who was arrested did not know each other.
Anyone who witnessed the incident or has information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
